An integrated approach to waste and energy minimization in the wine industry : a knowledge-based decision methodology
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The importance of waste management is growing rapidly for several reasons. These
reasons include the escalating cost of wastewater treatment and cleaning chemicals, an
emerging trend of onerous regulatory ...
Multivariate nonlinear time series analysis of dynamic process systems
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: Physical systems encountered in process engineering are invariably ill-defined, multivariate,
and exhibit complex nonlinear dynamical behaviour. The increasing demands
for better process efficiency and ...
Estimation of concentrate grade in platinum flotation based on froth image analysis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Flotation is an important processing step in the mineral processing industry wherein valuable minerals
are extracted. Flotation is a difficult process to control due to its complexity, meaning that the ...
On-line monitoring of hydrocyclones by use of image analysis
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Hydrocyclones are separation devices that are widely used throughout the chemical engineering and mineral processing industries. Although simple in design, the intricate flow structure of the device ...
Monitoring and diagnosis of process systems using kernel-based learning methods
(Stellenbosch : University of Stellenbosch, 2007-12)
ENGLISH ABSTRACT: The development of advanced methods of process monitoring, diagnosis, and control has
been identified as a major 21st century challenge in control systems research and application.
This is particularly ...
Multiscale process monitoring with singular spectrum analysis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Multivariate statistical process control (MSPC) approaches are now widely used for performance monitoring, fault detection and diagnosis in chemical processes. Conventional MSPC approaches are based on ...
Scale-up of mechanically agitated flotation processes based on the principles of dimensional similitude
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The use of dimensional analysis to scale-up mechanically agitated flotation processes
and to identify deficiencies in froth flotation plants was explored. The full range of
operating variables was ...
System identification and model-based control of a filter cake drying process
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: A mineral concentrate drying process consisting of a hot gas generator, a flash dryer and a feeding section is found to be the bottleneck in the platinum concentrate smelting process. This operation is ...
Analysis of process data with singular spectrum methods
(Stellenbosch : University of Stellenbosch, 2003-12)
ENGLISH ABSTRACT: The analysis of process data obtained from chemical and metallurgical engineering systems
is a crucial aspect of the operating of any process, as information extracted from the data is
used for control ...
